ADJUSTING THE GAUGE WHEELS
The cutting height of the mower deck can be set in
any of six height settings using the deck lift handle of
the tractor. The deck heights range from 1-1/2 inches
to 4 inches. The deck gauge wheel position should be
approximately 1/4 to 1/2 inch above the ground when
the deck is set in the desired height setting.
WARNING: Keep hands and feet away
from the discharge opening of the
cutting deck.
NOTE: The deck gauge wheels are an anti-scalp
feature of the deck and are not designed to support the
weight of the cutting deck.
Using the lift handle, set the deck in the desired
height setting, then check the gauge wheel and if
necessary adjust as follows.
• With the deck set at the desired height, visually
check the distance between the gauge wheels
and the ground. If the gauge wheels are near or
touching the ground, they should be raised. If the
gauge wheels are more than 1/2" above the
ground, they should be lowered.
• Remove the lock nut securing one of the gauge
wheel shoulder screws to the deck. Remove the
gauge wheel and shoulder screw. See Figure 34.
• Insert the shoulder screw into the one of four
index holes in the front gauge wheel bracket that
will give the gauge wheel a 1/4 to 1/2 inch
clearance with the ground.
• Note the index hole of the just adjusted wheel,
and adjust the other gauge wheels into the
respective index holes on the other gauge wheel
brackets on the deck.

DECK MAINTENANCE
Using the Deck Wash System
WARNING: When using the deck wash
system, never engage the deck from any
position other than the operator’s seat of
the tractor. Do not use an assistant or
engage deck in the presence of any
bystanders.
• Attach the nozzle adapter to a standard garden
hose connected to a water supply.
• Move the tractor to an area within reach of the
hose where the dispersal of wet grass clippings is
not objectionable to you. Disengage the PTO,
engage the parking brake, and stop the engine.
• Pull back the lock collar of the nozzle adapter and
push the adapter onto one of the deck wash
nozzles at either end of the mower deck. Release
the lock collar to lock the adapter on the nozzle.
See Figure 35.
Figure 35
• Turn on the water supply.
• From the tractor operator’s seat, start the engine
and engage the PTO. Allow to run as needed.
Disengage the PTO and stop the engine.
• Turn off the water supply.
• Pull back the lock collar of the nozzle adapter to
disconnect the adapter from the nozzle.
• Repeat the previous steps to clean the deck
using the nozzle at the other end of the deck.
Cleaning the Spindle Pulleys
Once a month remove the belt covers to remove any
accumulation of grass clippings from around the
spindle pulleys and V-belt. Clean more often when
mowing tall, dry grass.
